Exercise device

Abstract

A portable exercise device with a cylindrical and elongated main shaft and a plurality of central components that fit over the main shaft. Both ends of the main shaft are releasably attached handles. Each of the handles comprises a grip section that is cylindrical in shape and overlies a handle support. The grip section of each of the handles is releasably attached to the handle support, and the handle supports are releasably attached to the main shaft. Longitudinal axes of the main shaft and handles are collinear. Each of the handles comprises an attachment member that extends from a distal end of the handle and forms an arc. An inner circumference of the attachment member is circular except for a flat portion that is equal in width to the flat portion of the handle support. The handle attachment members are configured to releasably attach to the handle supports.
